Answer:

true

Step-by-step explanation:

The only regular (all sides equal and all angles equal) quadrilateral is a square. So all other quadrilaterals are irregular.

Answer:

Falsee, I believe.

Rhombuses are equilateral too...

Answer:

x = 25

Step-by-step explanation:

Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.

(2x + 15)⁰ + x⁰ = 90⁰

2x + 15⁰ + x⁰ = 90⁰

2x + x + 15⁰ = 90⁰

3x + 15⁰ = 90⁰

3x + 15⁰ - 15⁰ = 90⁰ - 15⁰

3x = 75⁰

3x / 3 = 75⁰ / 3

x = 25⁰

Now plug the x value in the missing angles.

2x + 15⁰

2(25⁰) + 15⁰

50⁰ + 15⁰

65⁰

According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.

65⁰ + 25⁰ + 90⁰ = 180⁰

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:

84 ft^2

Step-by-step explanation:

To find the area of this rectangle we multiply width and length

8 × 10.5 = 84 ft^2

Answer:

n has to be at least 16577.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

Out of n randomly selected students she finds that that exactly half attend their home basketball games.

This means that [tex]\pi = 0.5[/tex]

99% confidence level

So [tex]\alpha = 0.01[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].

About how large would n have to be to get a margin of error less than 0.01 for p

We have to find n for which M = 0.01. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.01 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]

[tex]0.01\sqrt{n} = 2.575*0.5[/tex]

[tex]\sqrt{n} = \frac{2.575*0.5}{0.01}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.01})^2[/tex]

[tex]n = 16576.6[/tex]

Rounding up

n has to be at least 16577.

Answer:

12m

Step-by-step explanation:

You can break this shape down into a square and a trapezoid. Frist you can find the area of the square by multiplying 2 by 5 to get 10. Then you would find the area of a trapezoid by doing Area = 1/2height(base1+base2). We can find the height by subtracting 5 from 9. (We do this because we know the side of the square is 5m) Therefore the height would be 4m. We know the bases are 2 and 4. From there you can plug those numbers in to the formula. Area=1/2 * 4 (2 + 4)

Area= 1/2 * 4 (6)

Area = 2(6)

Area = 12m

1/3

Step-by-step explanation:

11 - 7 = 4

4/12 -> 1/3

Step-by-step explanation:

here you have the answers

Answer:

[tex]A=12[/tex]

Step-by-step explanation:

The formula to find the area of a trapezoid is,

[tex]A=(\frac{b_1+b_2}{2})(h)[/tex]

Where ([tex]b_1[/tex]) and ([tex]b_2[/tex]) represent the two bases of the trapezoid, and ([tex]h[/tex]) represents the hieght of the figure. As one can see on the coordinate plane,

[tex]b_1=2\\\\b_2=4\\\\h=4[/tex]

Substitute in the given values, and solve,

[tex]A = (\frac{b_1+b_2}{2})(h)\\\\A = (\frac{2+4}{2})(4)\\\\A = (\frac{6}{2})(4)\\\\A = (3)(4)\\\\A = 12[/tex]

Answer:

y=x+10

Step-by-step explanation:

1.  4 x 31 is 124

2. 7 x 49 is 658

3. 16 x 48 is 608

4. 8(5 + w) is   8w + 40

5. 11(9 + d) is   11d + 99

6. 15(p + 4 + 2) is   15p + 90

7. Let's simplify step-by-step.

2x−4+3x

=2x+−4+3x

Combine Like Terms:

=2x+−4+3x

=(2x+3x)+(−4)

=5x+−4.

8. Let's simplify step-by-step.

4y−1−3y−2

=4y+−1+−3y+−2

Combine Like Terms:

=4y+−1+−3y+−2

=(4y+−3y)+(−1+−2)

=y+−3.

9. Let's simplify step-by-step.

x+2(x−4)

Distribute:

=x+(2)(x)+(2)(−4)

=x+2x+−8

Combine Like Terms:

=x+2x+−8

=(x+2x)+(−8)

=3x+−8.

10. Part A)

The jazz band sells 31 large boxes of fruit and 74 small boxes of fruit.

For each large fruit box, the price is $20 and cost is $x.

Profit is defined as Price - Cost.

So, profit for one large fruit box = 20 - x

Profit for 31 large fruit boxes = 31(20 - x)

Price of each small fruit box is $10 and cost of each small fruit box is $y. The profit for each small fruit box is 10 - y.

Profit for 74 small fruit boxes = 74(10 - y)

The total profit for 31 large boxes and 74 small boxes will be:

Total profit = 31 (20 - x ) + 74(10 - y)

Using distributive property, we can simplify the above equation as:

Total profit = 31(20) - 31x +74(10) - 74y

Total profit = 1360 - 31x - 74y

Part B)

Cost of each large box is given to be $9. This means x = 9

Cost of each small box is given to be $4. This means y = 4

Using the values of x and y in the profit equation we can find the profit of the Jazz Band.

So, Jazz Band's Profit = 1360 - 31(9) - 74(4)

Jazz Band's Profit = $ 785

Thus the profit of Jazz Band will be $785.

Have A good day!! Hope I helped!!! ^-^

Answer:

Answer:36.4

Step-by-step explanation:

Answer:

41%

Step-by-step explanation:

5 packs of crayons split among 12 people means we divide 5 by 12.

[tex]\frac{5}{12} = .4166666667[/tex]

we can round that decimal number to .41 which can be turned into a percentage by moving the decimals place.

.41 = 41%

Answer:

13

Step-by-step explanation:

arrange the numbers in order

8, 9, 11, 13, 14, 14, 15

find the number physically in the middle

Answer:

The median is 13.

Step-by-step explanation:

The way you can find median is by putting the numbers in order from smallest to greatest, then finding the middle point. If the number of data points is odd, the median is the middle data point in the list. If the number of data points is even, the median is the average of the two middle data points in the list. Using this explanation, you can put your numbers in order.

8, 9, 11, 13, 14, 14, 15

As you can see, 13 is the middle number in the list.

The answer is 207 ft^2

Step-by-step explanation:

Answer:

207

Step-by-step explanation:

Hey There!

So the first step is to solve for the figure with a length of 9 and a width of 15

15x9=135

The other figure has a length of 12 and a width of 6

6x12=72

No we just add them

135+72=207

therefore 207 is your answer
